As adorable as Colton Haynes is, it's kind of amazing how eager he is to lose himself in his Halloween costumes. Like, can you tell this picture of Fiona from last Halloween is the Arrow hottie?

Well, Haynes upped his costume game this weekend, when he attended a Halloween bash as The Little Mermaid's Ursula the Sea Witch.

Need proof it's him? Okay, but it ain't gonna be pretty.

Haynes was with the Walking Dead's Austin Nichols who thankfully did NOT go as a zombie.

Here's more Colton the Sea Witch goodness.
